Heliophanus Marshallii sp. nov. 
Plate XX, figs. 5-5b. 
<$. Length 5 mm. Legs 4132, nearly equal in thickness. 
This species has a long, straight, stout apophysis on the pa¬ 
tella of the palpus. 
In our specimens the cephalothorax, which has a black and 
glistening integument, has been rubbed, so that only a few 
white hairs on the thoracic part, and in a band around the 
sides, remain. The abdomen has three white bands, one in the 
middle and one on each side, all reaching the spinnerets. The 
spaces between the bands are black but seemj to havei been cov¬ 
ered with yellow hairs. The legs are dark brown except the 
tarsi, which are yellow. The palpus is black with snow-white 
hairs. The falces are short, and moderately stout, and are 
brown in color. 
II. Marshallii is almost exactly like II. debilis E. S. and 
H. patellaris E. S. in color, and each of these species has a 
pateliary apophysis. In debilis and patellaris, however, the 
apophysis stands out at a wide angle, while in Marshallii it 
extends in a line with the palpus. Marshallii, is larger than the 
other species and has dark legs with yellow tarsi. In debilis 
the legs are all light yellow, and in patellaris they are either 
entirely yellow, or entirely brown. 
This species is named for Mr. Guy A. K. Marshall, who' has 
made most valuable investigations in Mimicry and Warning 
Colors. We have two males from Durban.
